In the late 1990s, it was also marketed as plans and in kit form by Bell Aeromarine of Leicester, UK.[3]
The Z-21 is a single-seat, open cockpit 1920s-style biplane with fixed conventional landing gear with spoked wheels and a single engine in tractor configuration.[1] [2]
The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 5.51NaN1 span wing has a combined area of 9m2 and ailerons on the bottom wing only. The aircraft was designed for the 650NaN0 Volkswagen air-cooled engine, but other variants have been developed that use a variety of engines, including the 1100NaN0 Rotec R2800 radial engine.[1] [2]
Further planned developments include a tandem two seater, a four aileron version and a lighter weight version.[1] [2]
In August 2014 there were eleven Flitzers registered in the United Kingdom.[4]
